The criticism of Microsoft CEO Steve Ballmer just doesn't let up. He's just been rated the third worst CEO of more than 50 major tech companies by the site Glassdoor.com. Those ratings are based on what employees think of their CEOs, so there's clearly dissension in the Microsoft ranks.

Glassdoor.com puts together a "Naughty and Nice" list every year for technology CEOs, based on ratings that employees give to company CEOs on the Glassdoor.com Web site. Of the more than 50 CEOs of top technology companies, Ballmer's rating was way down toward the bottom, at third worst. He received a 35 percent rating, according to GeekWire, down from 49 percent a year ago. Only Yahoo CEO Timothy Morse at 31 percent, and Xerox's Ursula Burns at 28% did worse.

Glassdoor.com has more bad news for Microsoft as well -- the company didn't make the list of the 50 best places to work as rated by employees. The list covers all companies, not just tech companies. Facebook was number 3, Google was number 5, and Apple was number 10.

This isn't the first time Ballmer has been slammed by Glassdoor.com ratings. Back in April, his rating was 40%, which at the time was the worst of the CEO of any major tech company.
